Paintings
Lately, I’ve been spending a little time each morning drawing and painting before I begin making jewellery.
It has become a quiet ritual, a way to find a little calm before the day begins.
Over time, these small works have gathered, and I now feel ready to let them find a home with someone else.
Enjoy a colourful and poetic world of flowers, birds and fruit.
